From 001aac257cf8adbe90cdcba6e07f8d12dfc8fa6b Mon Sep 17 00:00:00 2001 From: James Bottomley Date: Sun, 2 Dec 2007 19:10:40 +0200 Subject: [SCSI] sd,sr: add early detection of medium not present The current scsi_test_unit_ready() is updated to return sense code information (in struct scsi_sense_hdr). The sd and sr drivers are changed to interpret the sense code return asc 0x3a as no media and adjust the device status accordingly.
